    I would hardly call using sand an amateur method. Less than ideal yes, but so is anything short of mandrel bending in the OP's situation. I was simply following the repair procedures laid by Babcock...

    Buy a Hypertherm, end of story. Theit machines are tested to some ridiculous standard and a 60% duty cycle machine will easily run non stop on a table.

    No its not but if the chuck closes down small enough to hold the part then what is the point? It's a one off repair type job. My first lathe didn't have a quick change nose so I had a 14" 4 jaw on it...

    I could be off but I was under the impression the whole idea was to transfer vibration out of the machine. Hence why large rotating equipment often has concrete pillars all the way down to bedrock.

    That would put you around a 5.5:1 diameter to CLR ratio. The OP is trying to achieve 3.25:1 That is a huge difference and I just don't see it happening without a mandrel

    Also the only time I ever run dual shield is if I can't get out of the wind but need to be faster than stick welding.....ie bucket, blade work. Luckily those days are behind me, if I'm welding now...
